Part 7/8:
Having accumulated a collection of these devices and their components, the speaker reflects on the history and potential of barium titanate and related materials in sensing and energy generation applications. While these technologies once showed promise for long-lasting and sensitive field detectors, waning interest and practical difficulties have limited their widespread adoption. Nevertheless, their development exemplifies innovative strides in piezoelectric and electrostrictive materials, paving the way for future explorations in sensing, archaeology, and energy harvesting.
